Hi
My boiler is noisy after changing the hot water cylinder a couple of months ago. I've got some Fernox boiler silencing stuff that you add via a radiator. The pack says close of rad valaves - open bleed valve and then attach pipe and mastic gun to ran. Open valve (the one you usually use to turn off & on) and inject stuff.
Has anyone done this? DId it go ok?
A search also found a suggestion to crack the radiator nut after shutting off valves to drain rad and then add it?
Anyone tried this method?
Thanks in advance
John
